  • Aqueous dispersions for simultaneously providing fibrous materials with a softening and hydrophilic finish, a process for their production and their use
    Patent number: 4966725
    Abstract: The present invention describes aqueous dispersions for simultaneously providing fibrous materials with a softening and hydrophilic finish containing(1) at least one quaternary compound with at least one long-chain alkyl residue,(2) a polymer or copolymer on the basis of alkylacrylates with alkyl residues having at least 4 C atoms,(3) optionally in addition an emulsifier which is other than (1) and(4) optionally a silicone which provides a hydrophilic finish.Furthermore, a process for the production of said aqueous dispersion is claimed.Using said dispersions, fibrous materials, especially cotton towelling fabrics, are provided with a particularly soft, velvety feel and very good to outstanding hydrophily.
